Bearing Life (L10)
Calculate the L10 rating life of a rolling bearing in millions of revolutions and operating hours, free online.
À propos de cette calculatrice
L10 = (C ÷ P)^p million revolutions, with p = 3 for ball bearings and 10/3 for roller bearings, where C is the basic dynamic load rating and P the equivalent dynamic load. 90% of bearings survive at least L10. In hours: L10h = 10⁶ × L10 ÷ (60 × rpm).
